Cookie Clicker Wiki

Every (un-heavenly) milk stage in Cookie Clicker

Milk is a valuable resource which unlocks the Kitten series of upgrades; these greatly increase cookie output rate in direct correlation to the amount of Milk the player has. Milk is gained by unlocking normal (non-Shadow) Achievements at a rate of 4% milk per Achievement. As of version 2.052, the total number of normal achievements that count towards milk is 622 and the maximum attainable Milk amount is 2,488%.

The Milk is represented by a wave-animated overlay at the bottom of the Big Cookie partition. The overlay gradually gains height as the Milk percentage increases. The milk changes color and name for every 25 Achievements, although this has no effect on cookie production. New Milk types and Kitten Upgrades have been introduced with new Achievements and the consequential higher possible Milk levels.


As the player gains more and more (non-shadow) achievements, Milk will change its appearance and flavor. The current Milk flavor and rank are shown at the top of the Achievements section in Stats.

After purchasing the Classic dairy selection heavenly upgrade, you may freely choose the flavor of Milk using the "Milk selector" switch. However, this is only a cosmetic change, and does not affect the information shown in the stats menu. Additionally, there are 9 more types of Milk added by purchasing the Fanciful dairy selection heavenly upgrade: Zebra Milk, Cosmic Milk, Flaming Milk, Sanguine Milk, Midas Milk, Midnight Milk, Green Inferno Milk, Frostfire Milk and Soy Milk. These new types of Milk are unique in introducing not only new colors, but new patterns to the Milk.

Each kitten upgrade's Milk Factor, multiplied by the Milk Percentage, provides a CpS production boost. These effects stack multiplicatively, with the Milk Percentage applied separately for each kitten upgrade. For example, say you have Kitten helpers, Kitten engineers, and 200% Milk (50 achievements). Kitten helpers multiplies production by 1 + 2 * 0.1 = 1.2, and Kitten engineers multiplies production by 1 + 2 * 0.15 = 1.3. Combined, these two multipliers will get you a total production multiplier of (1 + 2 * 0.1) * (1 + 2 * 0.15) = 1.2 * 1.3 = 1.56.

Note that this is not multiplying all the kitten factors by the milk percentage (which in this example would get you 2 * (1 + 0.1) * (1 + .15) = 2.53), and while the method used initially results in a lower milk percentage, the multiplier quickly becomes higher with the used method after the 5th kitten upgrade is purchased. With 350 achievements (1400% milk) and all regular kitten upgrades purchased, the CpS production boost is 2,693,564,425%. With all 622 achievements (2488% milk) as of v2.052 and all 17 kitten upgrades (including Fortune #103 and Kitten angels), the CpS production boost is 11,759,167,698,203%. You can check the overall Kitten multiplier in top of Achievements section in Stats.


There are modifiers that can increase the Milk Factor of your kitten upgrades.

Modifier Milk Factor multiplier
Santa upgrade: Santa's milk and cookies 1.05
Auras: Reality Bending / Breath of Milk / Both 1.005 / 1.05 / 1.055
Mokalsium, Mother Spirit: Diamond / Ruby / Jade 1.1 / 1.05 / 1.03
Garden plants (mature, clay) 1+0.0025W
W = # of Whiskerbloom

These are multipliers to individual Milk Factors of each of your kitten upgrades and stack with each other multiplicatively. For example, if you have Kitten managers, the Milk Factor would be 0.2* 1.05 = 0.21 with one of the 1.05 modifiers (Santa upgrade, Breath of Milk aura, or Mokalsium in the Ruby slot). With three 1.05 modifiers, the effective Milk Factor would be 0.2 * 1.05^3 = 0.231525.

With Diamond Mokalsium, Santa's Milk and Cookies, Both Auras, all kitten upgrades (including Fortune #103 and Kitten angels), and all 622 achievements (2488% milk) as of v2.052, the total CpS multiplier would be 164,190,867,250,320%.

The effect of Garden plants on Milk percentage is much more complex. The power of Whiskerbloom can be increased by Nursetulip, but Nursetulip itself will reduce overall CpS. See the following examples for detailed discussion. All examples assume:

  • 439 achievements obtained, 1756% base milk% (maximum as v2.021)
  • All kittens owned (including Fortune #103)
  • All 3 non-garden modifiers owned
    • Aura: Breath of Milk only
    • Mokalsium: Diamond slot
  • All plants are mature
  • The soil is clay.

Example 1[]

A full 6x6 plot of 36 Whiskerblooms has the modifier, fW, of 1 + 0.0025 * 36 = 1.09, and combining all other three non-garden multipliers will give the effective milk percentage:

The resulting Kitten multiplier will then be:

Which is approximately 3,919,378,731.

Example 2[]

To reach the highest possible effective milk percentage, the Garden should initially be planted as follows:

W=Whiskerbloom, N=Nursetulip

Each Nursetulip (in clay) boosts adjacent plants' effects by 5/4. Nursetulip's boosts persist for the tick after it is unearthed, and we can plant a budding Whiskerbloom in its place to both avoid CpS penalty from the Nursetulips and get more milk multipliers. The overall Whiskerbloom modifier will be:
Or approximately a milk effectiveness of +13.46%.

The max effective milk percentage which can be achieved is:

The resulting Kitten multiplier would be:

This is approximately 5,809,133,949.
(this is all outdated by several updates)

However, single Nursetulips in clay also reduce overall CpS by 1/40. In this arrangement, they reduce CpS by a factor of:

Which means the overall production multiplier is only fN * K ~ 2,976,619,930. Thus, despite having the largest possible Kitten multiplier, this setup is not viable for sustained CpS increase, as the amount of time without its CpS penalty is a maximum of 15 minutes.

Example 3[]

To offset the Nursetulip debuff, the best garden arrangement is:

W=Whiskerbloom, N=Nursetulip

The total Whiskerbloom modifier for this setup is:

The effective milk percentage for this setup is:

Which gives the Kitten multiplier:

This is approximately 4,458,570,563.

The Nursetulip factor will be:

With a resulting overall production multiplier of fN * K ~ 4,029,156,227, which is ~1.3536 times as much as the previous example, and 2.8% higher than the simple arrangement of 36 Whiskerblooms.



The top image shows the cumulative multipliers for each kitten upgrade, assuming all the previous upgrades were purchased, based on the milk percentage. In each group of 3 lines, the bottom line is the base multiplier, the middle line is the multiplier with either Santa's milk and cookies or Breath of Milk, and the top line is the multiplier with both. In the endgame, with 500 or more achievements, each kitten upgrade (except Kitten angels) at least triples production.


The bottom image shows the multiplier for the Breath of Milk dragon aura, based on the milk percentage and which kitten upgrades are active. The bottom line is the base multiplier, the next lines is the multiplier with Mokalsium, Mother Spirit at 5% or 10%. The lines for each kitten upgrade assume that all previous kitten upgrades are active as well. The base line assumes Santa's milk and cookies has been bought, but the 1.05 milk multiplier of Santa's milk would equal Mokalsium, Mother Spirit at 5%. Also, since Breath of Milk and Santa's milk and cookies have identical effects, their meanings on the chart can be swapped.

Dunking the Cookie[]

The Cookie-dunker Achievement is gained by accumulating enough Milk and adjusting the game window in a way that the Big Cookie is overlaid by the Milk graphic on a sizeable area. This can be done by zooming in a lot, reducing the height of the window, or reducing the display area by pressing F12.


Main article: Toys

Milk toys are interactive, physics-enabled objects that can appear in the left panel when Cookie Clicker loads. Toys have a 1/10,000 (0.01%) chance of appearing when the game loads, making them one of the rarest occurrences in Cookie Clicker. They don't do anything to alter gameplay. Reloading the page will cause them to disappear.


  • In the Stats menu, where other upgrades say "purchased", the kitten upgrades all say "purrchased".
    • Likewise, in the store, the kitten upgrades say "click to purrchase" instead of "click to purchase".
  • In the source code of the game, Sanguine Milk is referred to as "blood milk", with the image called milkblood.png.
    • This makes sense, as "sanguine" has the same etymology as "sang" which means "blood" in French, Orteil's native language.


  • The description for the Kitten wages upgrade is a reference to the meme "Cats can have little a salami."
  • The name of the "Kitten assistants to the regional manager" upgrade is a reference to the TV show The Office.
  • The description of the Kitten strategists "out with the old in with the mew, sir" is a reference to one of Alley Life's song named Out With The Old where a verse says "Out with the old in with the new s**t". The song was part of the tracklist in the videogame Tony Hawk's Pro Skater 2 released in the year 2000.
